Plastic knuckle pin lock

ABSTRACT

The KNUCKLE PIN LOCK is designed to fit an American Association of Railroads articulated locklift assembly&#39;s connector and up the bottom part of the attached toggle to a point where it would contact the bottom of the lock of the rail car knuckle. When the knuckle is in the closed or locked position, the knuckle pin lock when applied, would make opening the knuckle to separate a rail car from another rail car impossible. The Knuckle Pin Lock blocks the accidental or malicious disconnection of rail cars by blocking the ability of anyone or anything pulling up on the operating lever to open the knuckle. This mechanism can be made from plastic, metal, wood or any other rigid material. The thickness of the material depends on the type of material used. For instance, a plastic unit would be approx. 1/8″ thick. The larger “key” shaped holes are where fastening devices such as multi-purpose zip-ties would be threaded through and around the toggle and tightened. This secures the Knuckle Pin Lock to the locklift assembly. The smaller holes allow the device to be removed easily by breaking the plastic unit off when no longer needed on the rail car. When the unit is made from metal, the holes make it lighter and easier to handle. In this design, a more permanent fastening device such as a chain may be used.

This Knuckle Pin Lock can be made using plastic or metal as well as anyother rigid material with plastic being the preferred material.

It is approximately ⅛″ thick, 4½″ long and 2″ high. This device fitsonto an American Association of Railroads Articulated lockliftassembly's connector and up the bottom part of the attached toggle to apoint where it would contact the bottom of the lock of the rail carknuckle. When knuckle is in the closed position, the Knuckle Pin Lockwould secure the knuckle and subsequently the operating lever in theclosed position.

The Knuckle Pin Lock is held onto the toggle by a harness such as a“zip-tie”. A larger “zip-tie” is employed as a security device that isalso threaded through the Knuckle Pin Lock and is used as an emergencyrelease or a means of removing knuckle Pin Lock when no longer needed.

BACKGROUND OF THE INVENTION

This device pertains to transportation using railroad cars and theability to make the joints between the cars more secure from tamperingor accidental opening of the knuckles.

When this mechanism is installed on the knuckle pin, it becomesimpossible to open or separate the rail cars unless device is removed.

This device is very affordable and easily installed.

This device is effective in preventing electrical cable damage ongenerator sets of refrigerated goods when single rail cars are used.

Specialty purposes also include “continuous welded rail train sets wherecars are now “wired together with considerable time and effort”

This device can turn a single rail car into a continuous or“multi-platform” railcar of whatever size is required.

BRIEF SUMMARY OF THE INVENTION

Device installs onto an American Association of Railroads lockliftassembly's connector and makes opening a railcar knuckle impossibleuntil it is removed.

Device can be made of various rigid materials with plastic being theeasiest and most practical to work with.

Device has an extra large “zip-tie” attached which acts as a quickrelease in emergencies or when device is no longer needed.

Device has extra holes drilled into it to make it lightweight and easilyremovable.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

The drawing shows the piece of plastic cut into its final form. Thesmaller holes are ¼″

The two lager “key-holes” are ½″ and the notch is ½″×¼″ used to attachthe “zip-tie” on.

The upper notch is 1″ wide and ½″ deep.

the lower notch is ½″ wide and ¼″ deep.

DETAILED DESCRIPTION OF THE INVENTION

The KNUCKLE PIN LOCK is made from ⅛″ thick plastic. It has ¼″ holesdrilled into to make it flexible. It has two ½″ key-shaped holesopposite each other to thread a “zip-tie” through to secure to thelocklift assembly at its toggle. The upper 1″ notch and the lower ½″notch secure the device in place while in use. The devices overalldimensions are 4½″×2″ and can be mass produced.

1. The claim being made here is for the ability to secure operatinglevers in the locked position by immobilizing the A.A.R. articulatedlocklift assemblys ability to open by using this device.
